UCS LDAP Authentication "Domain Users" will not work

[Update: Cisco has opened a bug for this.  Expected to be fixed in 2.2 release, but you can track the progress here: CSCui60138]

 Summary:
In my previous post, I hypothesized that "Domain Users" simply contained too many members.  I was wrong.

Details:
After performing a couple of packet captures, I found that "Domain Users" was not an attribute returned in the "memberOf" property.  This seems to be a known response as "Domain Users" is typically classified as a "PrimaryGroup" and is therefore recorded in the "PrimaryGroupID" attribute.

Since UCS is only looking @ the "memberOf" attribute, "Domain Users" would not be returned.  I've made Cisco TAC aware of this discovery.  Whether it gets added as a bug or is simply relegated as a low hanging feature request is anybodies guess.  In the very least, I feel better to get this monkey off my back.

UCS Version:
2.1(1a)

UCS LDAP Workflow (as how it looked in my packet capture):

  1. UCS makes a LDAP bind call querying for the entered username for its "DN" and "memberOf" attributes.
  2. Once the information is returned, UCS appears to check the list of attributes in "memberOf"
  3. If UCS finds a match, it essentially grants whatever role access is granted to that LDAP group.
  4. UCS does query the LDAP group, but I'm unsure as to why it does this.  Seems redundant.

NSX-T: vCenter and NSX-T Inventory out of Sync (Hosts in vSphere not showing up in NSX-T)

Image
Summary: NSX-T loses synch w/ vCenter inventory, but statuses don't appear to show an issue.  Basically, you add a host to a vCenter cluster, NSX-T bits should start to automatically installing on new host.  Assuming you've created a Transport Node Profile and associated w/ the cluster.  The problem is that NSX-T doesn't see the new host and its link to the compute manager (vCenter) looks fine. Looks fine, Y U NO WORK!? So what's going on here?  This appears to affect NSX-T 2.5 and 2.5.1.  Cause is unknown. Workaround: Restart the cm-inventory service on each NSX-T mgmt/controller node using API or CLI. Details: If you were to query the status of the cm-inventory via API or CLI, you could query all 3 manager/controller nodes and get a status of running.  Even if the primary node associated w/ the VIP, if configured, is not necessarily in charge of inventory.  So you could restart the cm-inventory service till you are blue in the face and get nowhere be

MacOS: AnyConnect VPN client was unable to successfully verify the IP forwarding table modifications.

The VPN client was unable to successfully verify the IP forwarding table modification.  A VPN connection will not be established. Summary: I started running into issue utilizing Cisco AnyConnect on my Mac basically complaining about not able to overwrite IP forwarding tables.  This was on 4.6.x.  Since my VPN endpoints were not providing me w/ an updated client and w/ no access to Cisco Anyconnect downloads, my only option was to try openconnect.  It was totally worth it, here is why and how to set it up. PreReqs: Homebrew Installing OpenConnect: Launch MacOS Terminal brew install openconnect Getting VPN IP's/DNS Endpoints from AnyConnect: The information is typically located in your profile xml files located here: /opt/cisco/anyconnect/profile/somethingsomething.xml In the xml file, you are looking for "<HostAddress>typicallyaDNSName.com</HostAddress>" entry.  These are your VPN endpoints that you would need to pass to openconnect.

vCenter: Cluster Skip Quickstart Workflow via API

Image
Summary: Basically, whenever you reset vCenter, you might end up w/ a warning on a cluster running vSAN that's just annoying.  To circumvent, this from alerting, you need to disable quickstart.  Easy enough via UI, but API is a little weird here. Details: For one, code capture doesn't seem to understand this.  So no help there unfortunately.  Secondly, nothing named "quickstart" is in the API, so made this somewhat annoying to try and find.  Seems like someone had this question on the VMware communities forum 2 years ago w/ no answer.   Someone asked me internally, so I had to dig into it. Basically, two things: You can create a cluster w/ quick start disabled from the get go by passing a false boolean to a parameter named: "InHciWorkflow" via API/PowerCLI call Secondly, to "skip QuickStart" on an already created cluster, you can call a method called: "AbandonHciWorkflow" So yeah, you can see how "quickstart" and "HCIWorkfl
